Fit for almost any smartphone
Smartphones are pretty powerful music players. But those earbuds they throw in when you buy one leave a lot to be desired. The JBL Synchros S100a headphones are a smart upgrade for just about any smartphone. They feature an in-line remote control with a built-in microphone that's compatible with the iPhone® as well as Android™ and Windows® devices. So even if you change smartphones, you won't have to buy new headphones.
Proper sound from the proper fit
Naturally, you'll get more detailed sound from the Synchros headphones than those stock earbuds can offer. Plus, JBL's PureBass technology ensures you aren't left wondering what happened to all the low frequencies. Want to improve the sound quality of these headphones? Make sure they fit properly in your ear by experimenting with the included assortment of silicone and foam ear tips. A proper fit ensures a tight seal, which means more detail, better bass response, and less external noise getting through.
